Meeting Abstract 61.5  Sunday, Jan. 5 14:30  Somatosensory feedback during vocal production in a nonhuman mammal RIEDE, T; University of Utah t.riede@utah.edu Feedback mechanisms (somatosensory and auditory) are critical for vocal learners such as songbirds and humans in order to develop and maintain normal singing behavior or speech. Feedback is also important in some nonhuman mammals (primates, […]

Meeting Abstract 61.3  Sunday, Jan. 5 14:00  Prior experience with conspecific signals enhances auditory midbrain responsiveness to conspecific vocalizations GALL, MD*; WILCZYNSKI, W; Vassar College; Georgia State University megall@vassar.edu There is a long history in neuroethology of investigating how communication signals influence the brain and behavior. It has become increasingly clear that brain areas associated with sensory […]

Meeting Abstract 61.2  Sunday, Jan. 5 13:45  Motor control of an ultrafast spring-driven movement in smashing mantis shrimp KAGAYA, K.*; PATEK, S. N.; Dept. of Biology, Duke University, Durham, NC; Dept. of Biology, Duke University, Durham, NC k.kagaya@me.com Ultrafast movements are typically driven by springs that are loaded prior to movement. Given that muscles do not directly […]

Meeting Abstract 61.4  Sunday, Jan. 5 14:15  Development of laryngeal structure for call generation in the Túngara frog SMITH, H.K.*; WALLINGFORD, J.B.; RYAN, M.J.; Univeristy of Texas, Austin; Univeristy of Texas, Austin; Univeristy of Texas, Austin hksmith@utexas.edu The relationship between genes, development and behavior remains poorly understood. In frogs, evolutionary modifications in larynx development produce diverse larynx […]

Meeting Abstract 60.2  Sunday, Jan. 5 13:45  Wnt signaling in the leech posterior growth zone FLORES, V.R.*; WEISBLAT, D.A.; Univ. of California, Berkeley; Univ. of California, Berkeley vrf2@berkeley.edu Segmented groups (vertebrates, arthropods, annelids) are very successful taxa within the three bilaterian super-phyla (Deuterostomia, Ecdysozoa, Lophotrochozoa, respectively). Each of these also contains unsegmented taxa, raising the question of […]

Meeting Abstract 60.1  Sunday, Jan. 5 13:30  How the pilidium larva escapes an ancient constraint MASLAKOVA, S.A.*; VON DASSOW, G.; Oregon Institute of Marine Biology, University of Oregon svetlana@uoregon.edu The pilidium is a planktotrophic larva with unique morphology, development and metamorphosis, found only in pilidiophoran nemerteans (an order-level taxon with ~ 450 species). Nemerteans, a.k.a. ribbon worms, […]
